Abstract
Analog displays using the twisted-nematic mode have been constructed. Histogram or multibar displays are demonstrated. Within each bar, a narrow rectangular "vane" moves in response to analog voltages. These reflective displays offer low vane-width, sharp vane edges, and a highly legible white-on-black or black-on-white readout.
